1 Claim.

Example 40 parts of a-n-amyl cinnamaldehyde were gradually added to 24 parts of ethyl cyanoacetate cooled to C. One part of piperidine (catalyst) was added and the mixture then allowed to stand for 12 hours in a closed vessel at approximately 5 C. Considerable water had separated at the end of this period. The mixture was allowed to stand'at room temperature (20 C.) for an additional 24 hours. The reaction product was dissolved in ether, washed neutral (0.05% H2804), dried over sodium sulfate and distilled at reduced pressure. The a-n-amyl cinnamal ethyl cyanoacetate was recovered as a light yellow oil distilling at C. at less than 1 mm. pressure.

Although this new compound is especially effective as a contact poison for the control of insect pests, it may also be used for fungicidal and bactericidal purposes.

While the invention has been described with particular reference to specific embodiments it is to be understood that it is not to be limited thereto but is to be construed broadly and rerestricted solely by the scope of the appended claim.
